Hi, my boss this morning decided to change a light bulb and knocked the power cables out of the server. Windows 2008 R2 sbs

my problem is the 500gb mirror raid we have has a 100gb c drive and a 350gb e drive.
c = system partition
e - data partition.

we have no data partition any more, in disk management, when i right click on the e drive, it gives me options for
Mark partition as active
change drive letter
format
delete volume
propertise.

If i click change drive or propertise, i get

The oprtation failed to complete because the disk management console view is not up to date. refresh the view......
if the problem persists, close the disk console, then restart the management console or restart the computer.

We have already restarted the server.

it looks like the partition is there, but not.

any idea's how i can get it active with the data still in tack, if at all.

You say that you have a RAID mirror.

Is this RAID provided by a hardware controller or do you use a software mirroring solution?

Can you take a screen shot of the disk manager, so we get a clearer idea what you got?

You did not answer my question re RAID, but it appears that you have a hardware controller. Is your exchange data on the C: drive? What is stored on the E: drive? How old is your most recent backup?

To me it looks like the system has totally forgotten about this partition, which means that the partition table is probably corrupt. I would recommend checking the disk with a Live CD such as GParted, Ubuntu, Knoppix or a trial of a commercial server rescue tool.

Are your corporate email signatures appalling?

Is it scary how unprofessional your email signatures look? Do users create their own terrible designs and give themselves stupid job titles? You can make this a lot easier for yourself by choosing an email signature management solution from Exclaimer today.

Run a chkdsk /x on your C Partition (the server will have to reboot to do this and it can take some time), and when it is back up try assigning a drive letter to Drive E again. If that doesn't help, try opening a cmd prompt as administrator and then run diskpart and try assigning a drive letter through that. When you have diskpart opened, you can enter help to get the command syntax.

hi, I have discovered it was missing volume.inf from the windows\inf folder.
It was classing the partition as an unknown device in device manager.

once i put volume.inf and ran a scan new hardware it came back with all data in tack.

thanks for your suggestions.
